A character with the power to transform and reshape their body. This trope comes in a wide variety of forms, but can be classified by exactly what the character can transform themselves into.
Most commonly, a character is limited to a specific set of one or more "alternate" forms, or a specific "class" of things he can change into (animals, machines, elements, etc.) Sometimes, there's a specific feature that they are unable to conceal, like hair color, voice, or eyes that others can use to identify them regardless of what form they are in. If the only thing they are able to change is hair/eye color, they have Kaleidoscope Hair/Eye Colour Change.
Usually, the character can transform simply by thinking about it, but occasionally they may use a gadget or a magic phrase.
Magic Pants are almost always in effect, unless the shapeshifting character demonstrates or mentions they are simply molding what looks like clothing out of their body cells for the common decency of those around them. (In which case, it's best not to think too much about that... whoops, too late.)
Many Superheroes have this power, along with nearly all gods and Sufficiently Advanced Aliens. Some of them are Shapeshifting Tricksters and Reality Warpers.
Many with a flexible transformation scheme also have a tacked-on bonus ability to alter their shape in any way they wish; i.e., adopt a clay-like consistency and sculpt themselves blob-style. The stretchy, ultraflexible body of a character like Plastic Man or Elastigirl is a milder form. Others may use a Partial Transformation to "mix and match" elements of their human and transformed states.
Being able to form limbs into stabbing weapons and reform oneself after being blown apart by explosives has become an almost standard ability of the clay-consistency metamorph in recent years, probably due to the popularity of the T-1000 character from Terminator 2: Judgment Day.
Quite a few Shifters boast Elemental Powers, with water-based powers being particularly popular. A potent Healing Factor is also often packaged in, considering they can restructure their body at will.
Exactly where their extra body mass comes from (or goes) when a shapeshifter transforms from one size to another is known as Shapeshifter Baggage.
Can be used for Narrative Shapeshifting. The Shapeshifting Seducer finds picking up partners at bars is fairly easy, regardless of sex or preference, and is likely to be rather open-minded themselves about whom they choose. If they only sub-consciously choose to look like something, that's Self-Perception Shapeshifting.
Sooner or later, a Phlebotinum Breakdown may leave the character suffering Involuntary Shapeshifting or Shapeshifter Mode Lock, if only temporarily. If badly beaten or near death, they may have a Super-Power Meltdown and lose control of their power, resulting in a Shapeshifter Swan Song. If the character isn't very used to morphing shapes they may have Limb-Sensation Fascination after each change. Such a character might also be Otherworldly and Sexually Ambiguous.

- Kung Fu Pork Choppers: In Seasons 7-9, the pigs have the ability to shapeshift into stronger animalistic forms, with Hampton initially having all the transformations before they're spread throughout the team. Hampton transforms into a tiger, Hamgelina transforms into a crane, Glorious P.I.G. transforms into a bear, Snottingham transforms into a deer, and Pigcasso transforms into an ape.
- The eponymous main character of Lamput, being a blob without a definite shape, can shapeshift into whatever form he pleases and often does this to outwit the docs who are after him.

- Merlock from DuckTales the Movie: Treasure of the Lost Lamp has a talisman that allows him to turn into non-anthromorphic animals.
- One of the antagonists of Happy Heroes: The Movie, the aptly-named Transformation M./Shapeshifter, morphs into the shape of Doctor H. for much of the movie and does so well at mimicking his behavior that it even fools the Supermen at first.
- Pain and Panic from Hercules (1997) can turn themselves into any number of animals. They can even shapeshift together to make larger creatures they couldn't be alone.
- Jacklyn from Igor pulls this off using special pills.
- The Incredibles:
- Elastigirl can reshape herself into different forms like a makeshift boat or a parachute, thanks to her elastic powers. In the sequel, she takes on a glider shape similar to a flying squirrel to travel quickly through the city.
- Jack-Jack is classified a polymorph by Edna Mode in the sequel. He essentially shapeshifts on the molecular level. This grants him a wide range of different abilities such as setting himself on fire a la Human Torch or turning into a demonic-looking creature when he gets angry.
- Queen Watevra Wa-Nabi from The LEGO Movie 2: The Second Part is a brick-built character who can turn into... well, whatever she wants to be.
- Dave the octopus from Penguins of Madagascar, who manages to disguise himself as a human, although downplayed in that he needs to wear a wig and clothes.
- Merlin and Madam Mim from The Sword in the Stone are powerful magic users who can use magic to take on various forms. Merlin throughout the movie teaches life lessons to Arthur by turning himself and Arthur into various animals such as a squirrel, fish, and a bird. During her Villain Song Madam Mim performs feats such as shrinking, turning herself into giant, giving her face porcine features, and even making herself look young and beautiful. She also tries to kill Arthur (who is still in bird form) by turning into a cat. During their Wizard Duel, Merlin and Mim turn into various animals to fight each other. Mim cheats by turning into a dragon when earlier she said it was against the rules to turn into something like a pink dragon (she uses Exact Words by claiming she never said it was cheating to turn into a purple dragon). Merlin wins by turning himself into a germ, making Mim horribly sick and bedridden.

- The song "Shape Shifter" by They Might Be Giants is sung from the perspective of a person who suspects that multiple people and things around him are changing their appearance. Considering TMBG's love of the Unreliable Narrator trope, however, this may just be a metaphor.
- Songs from the Big Chair: One of the Sybil dialogue samples from "The Big Chair" (the B-Side of "Shout") is "The devil has the power to assume a pleasing shape".
- Quite a few dragons have this ability, depending on the story.
- In Japanese Mythology, tanuki ("raccoon dogs") usually have this ability; often kitsune (foxes), jorogumo (spiders), and housecats (bakeneko and nekomata) can do this as well.
- Happens in Celtic Mythology too from time to time.
- Loki, the Norse god of mischief, and to a lesser extent, Odin. Both gods held the power to change shape at will, and most of Loki's stories hinge on this ability.
- The gods in Classical Mythology were avid shapeshifters, to the point that often than not a mortal recognizing a major deity while they were still there was taken as a warning that something big was about to happen - and you were close enough to be collateral damage.
- Proteus was an ocean god that was particularly famous for his ability in this skill, most commonly to avoid being caught and interrogated by heroes who wanted to make use of his prophetic abilities.
- Selkies have the ability to change from seals into humans, then back again with the use of their coats.
- Pookas and kelpies both have the ability to shapeshift, with their defaults being yellow eyed horses living in marshes and swamps. (The difference being that Pookas are generally more benevolent than kelpies, who are just mythological douchebags).
- A similar Scandinavian water spirit known as the nøkken (in Norway at least; the name varies from region to region) could also transform into a horse, but his signature form was that of a handsome man with a violin. Its enchanting music would lure victims into the water, causing them to drown.
- Various African myths and legends include shapeshifters (almost invariably Always Chaotic Evil cannibalistic witches) who take the forms of lions, leopards, hyenas, jackals, crocodiles, snakes, bats, dogs, pigs, water buffalo, geese, grasscutter rats, wildcats, and sharks. They use these shapes to kill and eat people, dig up graves, destroy crops, and other heinous acts.
- Voluntary weretigers feature in the myths of China, Thailand, Bali, Java, and India.
- In the Balkans, there are legends of weather-controlling sorcerers who can turn into snakes, eagles, or other animals. Usually these are good guys who protect their home villages, but then they're also prone to attacking neighboring villages.
- In Mesoamerican folklore, the nahual is a person with the power to turn into an animal, usually a jaguar or puma.
- In many Chinese legends, certain taoists, Immortals and demons can perform the so called "72 Transformations" to transform into anything they like, change size or even turn their bodies into elements such as stone and metal. The name doesn't actually refer to the number of transformations, but refers to the fact that 72 is considered the number of perfection, as it's obtained by multiplying 9 and 8, the two highest single-digit numbers of Yang and Yin, respectively.
- Cool Kids Table: Void from The Chimera Program can reshape their body however they want, including becoming larger.
- Metamor City, the non-canon spinoff to Metamor Keep, takes place after the curse has been manipulated to the point where the cursed can assume their pre-curse forms for up to twelve hours at a time, but they need to spend an equal amount of time in their fully cursed form.
- The Thrilling Adventure Hour: Shapeshifting is the hat of Jupiter spies in the "Sparks Nevada, Marshal on Mars" episodes. On multiple occasions, Jupiter spy Jib Janeen infiltrates the group by posing as one of the main characters with the rest none the wiser until it's too late. This being a comedy series, the joke comes from the fact that the the characters are fooled despite the fact that Jib Janeen makes absolutely zero effort to hide his voice and mannerisms while in disguise. His initial appearances feature him singing the Sparks Nevada theme song as either Sparks or Croach and, in the latter case, being so hammy as Croach that Sparks' actor Marc Evan Jackson can't help Corpsing.
- Fire Emblem on Forums: Laguz characters and the monster classes from Clashing Ideals possess this as part of their class abilities.
- We Are Our Avatars: Indiana Jones could do this with a Wand of Polymorph and Ring of Polymorph Control. However, there are limits: it must be organic, can't exceed a certain natural power, and if a polymorph immune form, he'll be stuck in it.
- Champions does this with the Shape Shift power. This in and of itself only allows "cosmetic" changes (that may not even affect all senses), however — for the shapeshifter to be able to significantly change size and/or mass as well they would have to pick up Required Secondary Powers like Growth, Shrinking, Density Increase, or Stretching, and a shapeshifter who is also supposed to be able to adopt actual traits of multiple mimicked forms would be a prime candidate for a Variable Power Pool.
- Dungeons & Dragons is filled with creatures, races, classes, spells, and items that allow characters to shapeshift.
- Dopplegangers can only take humanoid forms, but can mimic any individual or type of humanoid they please, including clothes.
- Changelings (theorized to be descended from dopplegangers) can likewise assume other humanoid forms. Changeling wizards can confer a shapeshifting power to their Familiars.
- True lycanthropes (i.e. born, not infected) can switch between humanoid and bestial forms at will. Infected lycanthropes can learn to control their shifting to an extent, but voluntarily changing into hybrid or animal form automatically changes their alignment based on which variety they are.
- Deep dragons are natural shapeshifters, and gain a number of alternate forms as they age. The first is that of a winged snake, and they later gain access to a humanoid shape.
- Druids' Wild Shape ability allows them to take the form of wild animals. The prestige class "Master of Many Forms" focuses pretty much on that ability alone.
- Primevals can take the form of a single animal species at will, although it must be a prehistoric beast such as a dinosaur, megafauna or dire animal. They can only do this once daily when starting out, but gain additional daily uses as they level up.
- The Polymorph subschool of spells focuses on turning living things into other sorts of living things.
- Metallic dragons have the ability to turn into humanoids or animals once they become adults. Weirdly enough, metallic half-dragons are a lot less common than chromatic half-dragons despite the fact that chromatics do not have innate shapeshifting.
- A Hagunemnon or "Protean" kinda inverts this trope. Most shape-shifters keep a specific form until they make an effort to change it. Proteans instead change constantly; and while they can take a specific form if they want, keeping it for more than a few seconds requires constant effort and focus.
- Exalted:
- The Lunar Exalted have the ability to change into animals that they have eaten. Also humans, though they can eventually learn to add new human forms to their repertoire non-lethally. There aren't really all that many limits on what a Lunar can and can't turn into, as some of their Knacks allow them to acquire the forms of plants, elementals, demons, gods, raksha, and even geography.
"Hey, guys, I was just wondering — was this mountain always here? Because I distinctly remember a lake which used to be here..."
- The Lunars' patron Luna, the shapeshifting god/dess of the moon, is able to take virtually any form in existence (and some that aren't).
- The Lunar Exalted have the ability to change into animals that they have eaten. Also humans, though they can eventually learn to add new human forms to their repertoire non-lethally. There aren't really all that many limits on what a Lunar can and can't turn into, as some of their Knacks allow them to acquire the forms of plants, elementals, demons, gods, raksha, and even geography.
- Godforsaken: A character who Takes Animal Shape is a shapeshifter that can take the form of an animal, with full control over their transformation and mind in either form.
- Golden Sky Stories. Being that the players are magical animals (called henge), they can take on multiple forms such as Talking Animal, Little Bit Beastly and fully human.
- GURPS has lots of ways to do this but the Morph version of Shapeshifting allows the user to become virtually anything they have seen before (within point limits). There are numerous spells that allow the user to alter their shape as well.
- Marvel Multiverse Role-Playing Game: The Disguise and Shape-Shift powers from the Basic power set allow a character to take on the appearance of anyone or anything they wish.
- Night Wizard as a number of playable classes which can do this, most notably the Tamer/Magic Beast User, whose main gimmick is transforming body parts into various forms to grant himself various abilities.
- Paranoia. The Polymorphism mutant ability allows a character to change his shape enough to another humanoid form (for example, to impersonate another human being), but no more than that.
- RuneQuest: While nobody has seen him do it, there are multiple monsters with quite different faces who all call themselves Ralzakark and have similar personalities and positions running around, so people suppose that they are all the same one in different forms. Played with, however, in that the scorpion-armed Ralzakark claims that the unicorn-headed one stole his identity, but given how tricky that Ralzakark is, it might just be that he is making a double bluff.
- Sentinels of the Multiverse: The Naturalist can change between three animal forms at will, gaining a fourth during the OblivAeon event.
- The Splinter: All avatars have this ability. Each race has three forms that they can switch between. In fact, beings in the Realm that can't shapeshift aren't even considered truly sapient.
- Warhammer:
- The Changeling, a powerful Daemonic Herald of the Chaos God of Magic, can alter its form at will, using this ability to advance the plots of its nefarious master and generally spread as much chaos and misdirection as possible. It is said that the Changeling has taken on so many forms over the course of its existence that it has forgotten its original form.
- Warhammer 40,000: Vampires from early editions can alter their shape and appearance in order to resemble other alien species, which they use to infiltrate their societies.
- Warhammer Fantasy Battle: Quai Yin, the Moon Empress of Cathay, is a shapeshifting being from the moon; she typically appears in the form of a silver-scaled dragon, but if she has a "true" form at all isn't clear. She was also the one who taught shapeshifting to her mate Xen Yan, a true dragon, and to their children.
- The World of Darkness: Multiple games include variants of this.
- Mage: The Ascension: Mages can shapeshift depending on the magic used. Life is a pretty common one.
- Vampire: The Masquerade and Vampire: The Requiem have a vampiric discipline known as Protean, which allows for limited shapeshifting. Though the first few levels allow the changing of a single feature (eyes, claws, get fur and such), higher levels allow a character to shift into any form normally associated with vampires (i.e. wolves, bats, mist).
- Werewolf: The Apocalypse and Werewolf: The Forsaken have you play as a werewolf with five forms ranging through man to hybrid to wolf. Shapeshifting is controlled by the player for the most part. The game is based on werewolves, but sourcebooks allow players in the Old World of Darkness to play a variety of were-animals (big cats, ravens, rats, coyotes, bears, foxes, hyenas, spiders, snakes, crocodiles, lizards, sharks), most of which have either five or three available forms. New World of Darkness sourcebooks open up an even wider range of shapeshifters.
- World Tree (RPG): Bonstables can take on the form of either any Prime species or of silver-winged birds.
- Waldo from Muppet*Vision 3D at the Disney Theme Parks.
- The Academy of Magic: Witches can transform into various anthropomorphic animals and fantastical creatures by putting themselves in the creature’s shoes. Creatures that they can transform into include the Midnight Wolf, the Electric Deer, and the Vampiric Devil.
- Da Amazin OT Advenchr: In Appisote 19, Lite lands on Pluto after getting kicked in the ass BY an ass, where an alien shapeshifts into Nascar to fool him.
- Dreamscape: Keedran can change between an angelic and a monstrous form.
- RWBY: On the world of Remnant, living beings possess Aura, spiritual power that allows them to perform super-powered feats known as Semblances, and which can be amplified through the use of a substance called Dust. However, it's not magic, which everyone knows is just a fairy tale. What people don't know is that there's a secret brotherhood of very powerful people working very hard to make sure the world doesn't find out magic really exists. One member of this group, Qrow Branwen, has the ability to transform into a crow. Because it's a magical ability, he keeps it secret and only a select few people know about it; those that learn about the ability tend to get freaked out about it, strongly implying that the world views shapeshifting as impossible. Qrow's twin sister Raven, who abandoned the brotherhood long ago, has the same ability. Qrow has greyish-red eyes and Raven has ruby-red eyes; their bird forms retain these colours, giving away their identities to those who know what to look for. The twins were not born with this magical ability, but were granted it by the leader of the brotherhood, Professor Ozpin, who once possessed vast magical power that he claims has been dwindling over the many thousands of years that he has walked the earth; whether or not he can shapeshift or only pass on the ability to others is unknown.
- Strong Bad Email: In "shapeshifter", Strong Bad points out all the downsides to shapeshifting, such as the restrictive rules like only being able to turn into balloon animals, or half of a person, and the unintended consequences, like turning into a $100 bill, being picked up in the wind, and being stuffed in someone's sweaty pocket. Another "rule" that he points out is that all shapeshifters need to have a cool shapeshifting sound effect, such as "DWAYNE!"
- Supermarioglitchy4's Super Mario 64 Bloopers: The Imposter from the episode of the same name can shapeshift into anyone. He has even tricked SMG4 and Starman3 into believing that MarioMario54321 was acting weird and Mario was dancing to a Rickroll.
- The Backrooms: When The Landlord encounters "trespassers", he'll take on an eldritch form to kill them in a twisted way.
- The Chimera Bazaar
: Jaza is a shape-shifting being, but has forgotten its original form, which makes its gender questionable.
- Codex Inversus: Transmuter snails are capable of self-transmutation by waving their eyestalks in precise patterns, creating magical sigils and effectively casting spells. A snail may give itself climbing or jumping legs to deal with a tall obstacle, then a tadpole-like tail to cross a body of water, then turn that tail into a prehensile tentacle to reach a piece of food, then grow bristling spines over its shell to fend off a predator.
- Orion's Arm: Many Nanocyborgs are capable of shapeshifting, but like everything else in the setting, they're limited by the laws of physics.
- SCP Foundation:
- SCP-040-1a was created by SCP-040 ("Evolution's Child")
. It has polymorphic abilities and can change its size, shape, color, and texture as necessary to act as outer clothing (e.g. a sweater) for SCP-040.
- SCP-424 ("Nanomimes")
can take the form (but not the coloration) of any object or creature it has ever seen.
- When SCP-523 ("The Most Unhelpful Object On Earth")
escapes from containment, it changes its form to that of a useful object. When someone tries to use it for a specific purpose, it changes to another form that's not useful at all for that purpose.
- SCP-845 ("Liquid Polecat")
is a polecat that can change into a light brown liquid similar to water.
- When SCP-929 ("The Cuckoo")
comes within three meters of an animal it will rapidly change into a younger version of the animal. It will stay in that form until the animal it's imitating dies or it's attacked.
- SCP-953 ("Polymorphic Humanoid")
normally has the form of a small Red Fox, but can take the form of objects and living creatures, including that of an attractive Korean woman.
- SCP-1536 ("Doppelgängers")
can transform itself into any moving object or animal it sees, once every 16 minutes. SCP-1536 cannot be distinguished from what it copied by any known test.
- SCP-1537 SCP-1537-A
can change into an almost limitless variety of shapes. They can also increase their mass to up 3 times normal and make their skin as strong as steel.
- SCP-1961 SCP-1961-1
can take the form of any living creature of the same mass, including non-humans and SCP objects. They can retain human form for up to 4 hours but any kind of shock or strong emotions will cause them to melt down.
- SCP-2054 ("The Double")
is an entity capable of duplicating the form of a human being so completely that all of the science and technology of the Foundation can't tell the duplicate from the original. SCP-2054 is also able to copy the mind of the target well enough to convincingly impersonate them.
- All member of the original SCP-2750 ("Navajo Skinwalkers")
could change into at least five different animals found in the southwest U.S., such as crows, wolves, coyotes, eagles and foxes. Some members could change into nine or more types of animals.
- When SCP-2757 ("Dr. Wondertainment's Projector Fantastico™")
is used with SCP-2757-1e (the film The Valiant Crusaders), one of the powers gained by the experimental subjects is shapeshifting.
- SCP-040-1a was created by SCP-040 ("Evolution's Child")
- Scrub Club:
- Played straight for Gel-Mo, who can shapeshift into anything he likes (although he's still see-through and gooey).
- Downplayed for Squeaks who can turn into different kinds of soap, but only soap.
- Even more downplayed for the rest of the Scrub Clubbers, who can only turn into one thing (Taki always turns into a clock, Hot Shot and Chill always turn into faucets, etc).
- CellSpex can switch from her human avatar to her pony avatar at will, when she reviews an episode of My Little Pony: Friendship Is Magic. Though she apparently had to learn how to do this at will at some point, as the first time it happened, it just sort of... happened.
Cell Spex: Really? So this is mandatory for anyone who wants to analyse an episode? [sighs] Whatever.
- Mandela Catalogue: Alternates have this ability to take the form of their victim's friends, family, or even the victim themselves, with only a slightly different look than the person they mimic.
- Save The Supers: Morphman has this power, except that he always takes the shape of objects, still recognizable by their color scheme. This means (beyond an extra in the first episode) that there is no actor playing him; all his appearances are as (mostly) inanimate objects the rest of the cast interact with.
